Naomi Sterling and John Bancroft are lovers. The girl loves frivolous things and Bancroft, a divinity student, finally estranges himself from her by his continual efforts to preach to her. Attracted by Hugh Wiley, a gambler, from a nearby city, Naomi finally elopes with him and eventually becomes known as the gambling queen. The girl's one ambition in life is to hoard up her wealth against the day when she shall lose her beauty and her popularity. Bancroft has plunged into religious work. He has become famous as an evangelist and has been trusted with the combination to the vault of the great tabernacle over which he presides. Learning this fact, Wiley inflames the mind of Naomi against Bancroft on the false ground that he has spurned her because of her life. He plans to have Naomi lure Bancroft to her gambling palace on a pretense, to overpower the minister while he is in there, steal the combination and loot the tabernacle. Furthermore, Wiley arranges to have the executive board of the tabernacle informed when the minister is in the gambling den, and to have the place raided by the police while he and his pal, McCarthy, rob the tabernacle. But the minister is too strong to succumb to the temptations of Naomi when he reaches her apartment, and his spiritual power wins the repentance of his temptress. Wiley, realizing that he is losing, springs upon Bancroft from behind and gets the combination away from him while his confederate alarms the police and the executive board according to the plan. But Naomi spirits the minister away through a secret passage, rushes to the tabernacle too late to prevent the robbery, and makes the great sacrifice of replacing the stolen money by her own ill-gotten hoard before the bewildered police and board officials arrive at the vault. In the final great moment of spiritual exaltation, Naomi has realized the greatness of Bancroft's love and of his power. Meanwhile Wiley, in an attempt to steal the loot from McCarthy, has wrecked the automobile in which they are fleeing and is killed.
